CHARLES MILLER, OF AUBURN, NEW YORK.

DUMPlNG-WAGON.

SPECIFICATION forming part of Letters Patent Ihl'o. 278,253, dated May 22, 1883.

Application filed March 30,1883. (No model.)

To all whom it may concern:

Be it known that I, CHARLES MILLER, of

Y Auburn, in the county of Cayuga and State of dumping-wagon with one side of the body re-' moved, and Fig 2 is an end view of the same.

Similar letters of reference indicate corresponding parts in both the figures. I

My invention has relation to dumping-wagons; and it consists in the improved construction and combination of parts of a body and dumping mechanism, adapted to be attached to the running-gear of a common wagon, or a railroad-car, as hereinafter more fully described and claimed.

In the accompanying drawings, the letters A A indicate two pairs of polygonous wheels journaled in bearingsin the frame of the wagon, two in the front end and two in the rear end of the wagon;

Two endless chains, B B, run over these wheels, and the links 0 of the chains are of the same length as the polygonous sides of the wheels, so that when the wheels are rotated each link will rest upon one side of the same as they pass over them. I

A cog-wheel, l), is fastened upon the shaft of the forwardpair of wheels and is engaged by a bar, E, pivoted upon the frame and forming a handle at one end, while the other end is provided with a few cogs engaging the teeth of the cogwheel, serving to hold the wheels from revolving when engaging the cog-wheel, while it may be raised out from the teeth when the wheels are revolved.

The links of the chains are connected for a space as long as the body of the wagon by fiat cross-pieces F, of the same width asthe length of each link, forming a flexible bottom for the,

body, and, to sustain the weight of the load placed upon the said bottom, longitudinal rails G are fastened under the chains, having a series of rollers, H, journaled between them, under each chain, which travels over them, while the rails are supported by means of cross-bars I, passing under the bottom of the wagon, suspended by upright bars J, fastened at their upper ends to the top edges of the side pieces, K, of the wagon-body, thus bringing the weight of the load to rest on the top and sides of the body. At the front end is hinged the front end-gate, L, upon a bar, M, passing across the body from the top edges of the side pieces, the lower end of which gate is provided with rollers N, which allow the bottom to slide under it without lifting the gate.

The rear or tail gate, 0, is likewise hinged upon a. bar, P, crossing between the upper edges of the side pieces, and is held in place by a latch, Q, pivoted upon the gate upon a bolt, R, passing through it, near the one end, into the gate and engaging with both its pointed ends into two vertical slots or notches, S, one in each side'piece of the body, and operated. by a cord or chain, T, fastened to the longer arm of the latch, passing through a bail or small pulley, U, upon the edge of the side piece, down the side of the same, through an-' other bail or pulley, V, whereupon it is fastened to the one end of a lever, W, which operates a clutch for the dumping mechanism, so that when said clutch is thrown into operation, moving the bottom, the latch is raised, allowing the gate to be swung out and the load to be dumped. This clutch consists in a cog-wheel, X, turning with and sliding upon the shaft Y, upon which the rear wheels A are fastened, and having a grooved sleeve, Z, in the groove of which the end of lever W projects, sliding it laterally upon the shaft, so that when movedoutward it may engage a eogged rim, a, upon one of the hind wheels ICO sired, only one man being necessary to operate it, as the tail-gate is opened automatically the moment the dumping mechanism is thrown intogear.

Having thus described myinvention, I claim and desire to secure by Letters Patent of the United States- 1. In a dumping-wagon, the combination of the flexible bottom fastened upon an endless belt passing over wheels in the forward and rear end of the wagon, the supportingrails having rollers journaled between them, upon which the endless belt travels, and the crosspieces supporting the said rails, and having upright ends fastened to the upper edges of the sides of the wagon-body, as and for the purpose shown and set forth.

2. The combination of the swinging tailgate O, having latch Q, pivoted upon it, the pointed ends of which engage slots in the side pieces of the body, the operating cord or chain 1, fastened to the longer arm of the latch and passing over the side piece of the body, and

the clutch-operating lever W, to the end of which the cord or chain T is fastened, as and for the purpose shown and set forth.

3. A dumping-Wagon consisting of the polygonous wheels A A, endless chains B, bottom sections, F, rails G, rollers H, supporting-bars I J, side pieces, K, swinging end-gate L, having rollers N, swinging tail-gate 0, having latch Q, cord T, clutch-lever W, cog-wheel X, having grooved sleeve Z, cogged rim to, fastened upon one of the hind wheels, cog-wheel D, locking cogged lever E, and crank 2), all constructed, combined, and arranged to operate substantially as and for the purpose shown and set forth.

In testimony that I claim the foregoing as my own I have hereunto affixed my signature in presence of two witnesses.

CHARLES MILLER.
